This heat exchanger is really well built. I am not using it for a pool but this heat exchanger will be perfect to use to capture the waste heat from my Diesel Heater exhaust in my RV. I am using this as a air to air heat exchanger. Thanks for making such a great well made product. N.S.
The product was delivered before the time stated. Well packaged. I installed the product to heat my Hydroponic water tank. It is functioning well. I would buy another if i need another one.
